This assembly holds 4 Raspberry Pi Zero W and camera pairs in a 4 inch tube for a rocket launch. It holds the camera at a particular offset in the tube to allow 4 simultaneous videos or still sequences during a high altitude launch. It easily survived a 20G launch and returned video.
Each Rpi/Camera pair is held securely in a lidded enclosure that ensures that it does not have any "wiggle room". The lid is a press fit and each enclosure snaps into the aft and forward rings that keep the cameras aligned and mounted to a seal ring in the tube.
Included is a shorter enclosure that was used elsewhere in the rocket, but can also be used as a stand-alone mount for the Rpi/Camera.
Other mounts typically align the camera lens on the opposite side of the enclosure after bending the camera cable over. I chose to keep the cable straight and put the lens on the other side of the assembly (in this case the outside) as it fit the need better.
Note that the enclosure ensures that the SD card will not move even under high G loads.
I'm happy to supply design files if needed for design modifications for different uses.
Snap in mounts for each enclosure in the ring use a 45 degree lug so that no supports are necessary when printing the rings.
